Tulsa Botanic Garden, Botanical garden in Osage Hills, Oklahoma, United States.

Tulsa Botanic Garden covers 170 acres (69 ha) in Osage County, Oklahoma, about 8 miles (13 km) northwest of downtown Tulsa at 3900 Tulsa Botanic Drive. A 7-acre (2.8 ha) lake and a 1,200-square-foot (110 m²) visitor center opened in 2009. The grounds include the 3-acre A.R. and Marylouise Tandy Floral Terraces, the Children's Discovery Garden, the Bumgarner Family Foundation Lotus Pool, the Stanford Family Liberty Garden, and the 2-acre Jim and Cherry Bost Arboretum.

The garden was established in 1999 initially as a research and education center for Oklahoma's centennial commemoration. Significant expansion came in 2004 when a large land donation created the current layout.

In 2007 the Assistant Principal Chief of the Osage Nation performed a Blessing of the Land ceremony on the donated Persimmon Ridge tract before construction began. The garden's spring display, Tulsa Botanic BLOOMS, plants over 200,000 bulbs, and each autumn visitors vote in a scarecrow contest with figures made by community members.

The garden lies at 3900 Tulsa Botanic Drive, at the junction of N 52 W Avenue and W 43 Street N, about 8 miles northwest of downtown Tulsa in Osage County. Water and electric mains reached the site only in summer 2014; before that, water was trucked in and a portable propane generator supplied power. A 3,200-square-foot outdoor shade structure shelters plants that cannot take full sun.

The Bumgarner Family Foundation Lotus Pool features floating plant arrangements and aquatic species integrated into the larger water system. This area showcases water-based growing techniques that connect smaller water features to the main lake.
